GROUT, F CHICAGO, ILLINOIS, ASSIGNOR TO KELLOGG SWITCEBOARD AND SUPPLYCOMPANY, 0F CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS SOCKET Application filed September 27, 1926. Serial No. 137,911.

My invention relates to sockets and more particularly to sockets adapted to receive and support audion tubes or the like, and an object of my invention is the provision of a socket of the above type'for resiliently supporting an audion tube in order that vibrations and shocks will be absorbedwithout materially affecting the elements of the audion tube. Y f

1c A feature of my invention is the provision of a flat resilient member by means of which the 'tube supporting member' of the socket is resiliently supported from the base to permit the supporting member to yieldingly move in' alldirec'tions. y I

` Another featureof my invention is the provision of a novel tubeksupporting member which is secured to the resilient member for yieldingly supporting the same. f Still another feature ofmy invention is the provision of a novel arrangement in which f flexible conducting members carry the external circuits to the contacts of the tube supporting member'independent ofthe resilient member.

The above features of my invention as well as others not specifically pointed out will be more fully described in the ensuing specifica tion.` Y

3o For a more complete understanding of my invention reference may be had to the aecompanying drawings in which like reference characters inthe several views denote like parts and in which: i p

Fig. 8 is a perspective view of the contact carrying disk, and y Fig. 9 is aperspective view of the member for receiving the contact terminal pins or prongs of an audion tube.

Referring now more in detail to the draw-` ings, the seeket'of my invention as illustrat ed comprises a base B of suitable moulded insulating material, having the supporting lugs or legs 8 and 4 on the bottom side thereof, the legs 3 being provided with orifices 5 forthe reception of screws by means of which the socket base and itssupported parts maybe secured te a mounting base or sub-panel.

The tube socketsupporting member T comprises an inverted cup shaped member 7 and a contact carrying disk member 8 which when assembled as clearly illustrated in Figs. 6 and 7 form the means for supporting an audion tube. he cup shaped member 7 is provided with four integrally formeel downwardly eX-` i tending ribs 9 positioned at right angles to `each other, the said ribs 9 extending below therim 10 of the cup shaped member 7 a short distance. The faces 11 of the ribs 9 are pro-` vided with semi-circular grooves 12 which are aligned with orifices 12 in the bottom 13 of the inverted cup shaped member 7 `for purposes as will presently be described.

.The face 8 ofthe disk 8 is provided with an embossed or raised portion 14 which conforms with the contour of the ribs 9` integrally formed with the cup shaped member 7 Adjacentextending ribs 15 of the embossed portion 14 on the face 8 of the disk 8, form substantially triangular shaped depressions 16 in `which the substantially triangular shaped bases 18 of the L shaped spring contacts 17 are positioned and rivets 19 which pass through suitable orifices in the disk 8` andbases 18 of spring contacts 17 secure .theu

said springs 17 to the base 8. The edges 2O lfzlof the bases 18 of the springs 17 engage the edges 21 of the extending ribs 15 of the embossed portion 14 of the disk 8 and prevent the springs `17 from turning about the rivets 19 which secure them to the disk.

The inverted cup member 7 is provided ico with depending threaded stud 22^vvhich is secured thereto during the moulding of the same, and a central orifice 23 in the disk 8 and the free endsj27 of the springs 17 'secured-to its depending cylindrical portion 24 is adapted t receive the threaded stud22. kOne of the'ribs 9 of the cup jmember 7 is provided With a lug` which is adapted to register With an orifice 26 in one of the embossed ribs 151011 the 4disk 8: I'T oassociate thedisk.8 andy l@ fitsy supported; springjcontacts 17 With'the cup i member 7 the disk is positioned on the stud 22'so as to place the lug 25 on the rib 9 of the cup member 7 substantiallyv kin alignment with the'orice 26 inthe embossedfrib 515- ofthe disk` 8. l/Vith thedisk 8 thus positioned the same is new Vmoved along the stud 22 to permit the' disk 8`to enter the substantially triangular recesses 28 inthe 'cup member 7 formed by tlie ribs' 9' integrally/formed Atherewith and thevvall 29 of lthe sameL V'The' free ends 27 of the springs 17-When positioned in the recesses 28engage the faces' 11 ofthe ribs 9 in'the'cup f member 7 and alsospanl the semi-circular grooves 1 2`therein asis clearly illustrated in y Fig. 6. rWhen the disk 8and its supported springs 17 .are in 'this' position relativeto the ribs jnthe c'upwmeinber` 7 the disk 8 is turned in a clockwise direction on the stud 22 in relation tofFigQ 6 to place the lug 25 on the rib 9 ofthe cup member 7 in alignment vvith the oriiicef26 in the embossedrib 15 on thev disk 8.

The-movement ofthe disk 8 relative to the cup member l7 places thefree ends 27 ofthe springs `r17 under Ytension and the further f lniovement ofthe ydisk8 alongtlie stud 22 ynovv. permits the lug 25 to enter the orii'ice 26 in v s the disk 8 as clearly illustrated in Fig. 7. The

tensionof the springs 1 7 is such as to causethe f reeends 27 thereof to firmly engage the respective faces i1 of the ribsV 9 thus'preventing the disk8 from moving longitudinally along the stud 22 due tofthe frictional engagement vof the free ends Y 27 of the springs 17 With the faces 11 of the ribs 9 to hold the disk-8 and its supported Asprings 17. in association with thecnp member 7 runtil 4thisiiiiit member T is secured to: its springl supporting member as Will now `be described. Attached to the botloop meiiib'ers337 3 1and 35, l36. The Vbase B isgprovidedvvith integrally formed depending lugs 37 and suitable rivets 38 passing through orilicesin the base Band lugs 37 and the respective end portions 30 and 31 of the member C secureI the member on the bottom of the base B. The base Bis provided With a central orifice e() Whichis adapted to` looselyV receive the disk portion 8 of the tube supporting member T and vvith member T thus poe" sitioned in the central orifice e0' of the base B the depending 'cylindrical portion 24 ofthe disk` 8 engages the intermediate portion 32 of the member C.r The protrudingportion of the threaded stud22 projects through a suitable orifice 41 iii the intermediate portion 32' of the member VC and anut 4:2 having threaded 22jsecuresz=the tube supporting ymember T to engagement with theend'of the threaded studY v the resilient member C.' The nut Ll2 in addi-l @tion to Vsecuring the member T asa Whole to the resilient member C also secures the vdisk 1 8 ai'idfeu'p member`7 together. The'cylindiical depending portion 24 of the disk 8 isalso e provided lWith 'a lug 4l3which is adapted toYV enter a suitable 'orificelll in the intermediate portion 321`oftheresilient'member C to prevent the memberT from'r'otating in "the-Orisy Y e5Y the 'tube vsupporting member T are adapted to iiee 10.

VA pair of projecting ears 215 integrally formed with the base B lie beneath `the linterresilieiit member@ lto be flexed.- This dovvn- Ward movement is limited as'the diameter of the cup member 7 ffthe supporting niem-Y ber'T is slightly larger'than 'the central orifice j l0 inthe 'base B which vpermitsfthe rim '1G4 of the cup member 7 to enga-ge the top face mediate ]g '0'i tioii 32k ofthe resilient member C and when a tube is removed fromlthe socket' memberfT; the pull exerted fon the tube to *Y reinovethe same will causethe resilient'member C to flex but this iexure islimited' as the intermediate portion 32 of theresilientmemV e ber C Will engage the projecting ears i5 and 'thus prevent excess iiex'ure ofv theresilient member C as the tubelis Withdrawn.

As the tube supporting'member-,T is secured tothe resilientmemer C as before described :this resilient member C effectively cushions thev audion tube supported 4Vin the member T against a blow from any direction. The loop members 33, V311' and 35, 36 vvhichj connect the respective end yportions. 30 aiid 31 and are secured to the base B at the irltermediateportion 32 produce this cushion ing effect. The'loop members 33, 3 4 and 35, 36 thus permit thel tube supporting member T to. yield slightly toward .or'faWay from .j
